I have two Explorer.Series and want to divide the first series with the second series containing 0.
series0 = Explorer.Series.from_list([1, 2, 3])
series1 = Explorer.Series.from_list([0, 1, 2])
Explorer.Series.divide(series0, series1)
Then it throws an error,
thread '<unnamed>' panicked at 'attempt to divide by zero', /rustc/dc80ca78b6ec2b6bba02560470347433bcd0bb3c/library/core/src/ops/arith.rs:507:1

I think NaN
or Infinity
is the right result for dividing by zero. But I don’t know how to get that result with Explorer.Series.divide/2
.
